IMPROVE!) TURNOUT FOR STREET-RAILWAYS.

L The Schedule referred V'to in these Letters Patent and making part 0f the same.

To all persons to 'whom these presents mayof'me:

Be it known that I, WILLIAM TUTTLE, of Boston, of the county of Suolk, 'and State of Massachusetts, have invent-ed a new and useful Improvement in Street- Railways; and do hereby declare Athe same to be fully described in the following specification, and represented in the accompanying drawings, of which-- L Figure l denotes a top View of atrack and turnout, proded with my improvement, the object of which is to do away with the usual switch or tongue, and to protect the wedge terminus of the main track rail at junction of theturnout, from being crushed or injured -by the wheel-treads 'while passing over it.

vFigure 2 is a s ide view ofthe wheel-lifter or double inclined plane, applied to the junction-piece D, llereinafter mentioned, and intended for the dange of the wheel to run on, so as to keep the tread out of contact with the nose of the junction-piece while running over it.

v In the drawings- A A and BB denote the main track rails, C being the outer railof a turnout.

Instead o continuing the rail A parallel to the railv B B', I, at some twenty' feet from the nose aof the junction-piece D of the turnout C, and main rail A', commence to increase the wid li between the lails B B and A, and gradually increase such lwidth to the breadth of the groove d, which is between the'part .D

and the rail C; that is, from E to F, a distance of about' twenty feet, I arrange the rail part E F alittle out of parallelism with the rail B B', causing 'the rail E F,

on approaching the point a, to diverge vfrom the rail l The arrangement ofthe part E F, in manner as described, enables the car to readily take the turnout, as, in passing tothe latter, the driver of the car bas only to keep his wheel-anges, which are next to the rails E F, borne against suchguide-rail. f

So, in passing along the main track without intention. to take thev turnout, the driver should keep the otheranges of the wheels borne up to the rail B B.

The 'car will then pass clear of the turnout.

There is applied to the part D, and against its inner edge, a double inclined plane or wheel-lifter, G, cornposed of tworeversed inclined planes, e f, arranged' in manner, and with respect tothe nose a of the piece D, as represented.

In passing over the junction-piece D, the wheel-flange will run up the plane e, and next down the plane f, and in doing so, will keep the tread of the wheelentirely clear of the noseor point a, and thus prevent such from being crushed or broken down bythe wheel.

I claim as my. invention- The combination and arrangement of the wheeltread lifter G, made Vas described, with theturnout and main rail junction-piece D, as explained. W'M. TUIITLE.
